How are the aftermarket Lithuum batteries in performance? Is it even worth rebuilding them?
I have seen them at two separate Sears now along with a reciprocating saw and a 5 pc set with a work light. I just got the new hammer drill (mainly out of curiosity, plus I had a TON of points to use), drill, and 1/4" impact driver which I had when they first hit the website (also had a lot of points to use). I like the 1/4 impact as it is much lighter than my C3 version but lacks the bit holders in the handles which I do not like. Power and battery life is decent out of all with the hammer drill having a 90-in/pounds more than the ten-year old version it replaces. I teach high school wood shop and the new 20v seem to be holding up as well as the C3 units so far.
Necro-post, or whatever it's called... I did a search on Craftsman C3 tools and found this thread about Craftsman batteries. I just got in two days from amazon prime, two Li-ion batteries and two Ni-cad batteries for my collection of Craftsman cordless tools, most of which are C3, but I have a few older ones that are only Ni-cad. I ordered off amazon prime, from sellers who had about 1,000 buys, and a majority of + reviews. The Ni-cads are 3.7 A/h and the Li-ions are 5 A/h. They came charged, the Li-ions have a switch to display power level via 4 LED's.
I tested the batteries briefly in two C3 tools, a 3/8" right-angle drill, and a 1/2" drill. The Li-ion batteries seemed to 'torque' a bit more than the Ni-cad's did, but I was pleasantly surprised to have all-four report for work. No additional charging required. I will throw them in their respective chargers and top 'em-off. I'll give them a workout on some upcoming around the houses work and see how-long they last on charges.
I was moved to try the amazon prime route as I had tried at two different Ace Hardware stores to find the Li-ion Craftsman XCP batteries. The one Sears store in town still open in Miami had nothing on the floor or in the online tool catalog. At the Ace Hardware, I could only find one battery, it was something like 2 A/h for $87 out-the-door. No-thanks!
I had previously searched online and found really only import stuff at a reasonable price, and very-little XCP Craftsman batteries inventory. I went to amazon prime, made my order and in two days, I had 'em. The price was four batteries for the same price as
one XCP battery of minimal size from Ace Hardware.
I've opened both types of cases to see what would be involved in a swap-out, but for the price, I decided that it wasn't worth it. I've read stories of the Li-ion counterfeit batteries for the Sanyo 18650 batteries, and then there's removing the spot welds, and (I guess) soldering new strips on, which intimidates me a bit, as I don't know the particulars, and I would hate to have a battery explode on me because I overheated it trying to save a few bucks, attempting a solder job.
I'll try to give 'em a workout soon and come-back to report. I hope they last a couple of years. I don't want to have to switch to a new platform.
